Question

Sapling Learning where classify these systems as reac or product-favored at 298 K. lfthe drection possible, cannot be determined from the information given, classify the reaction as insuficientinformation'. Insufficient information Product-favored xt Reactant-favored A(g) B(g) C(g) 3C (g (g) B(g) 97 kJ 3C(g) 2A(g) B (s) 2A(g) 2B (g) 193 kJ AHD Exit O Previous Give Up & View solution Try Again 0 Explanation An increase in entropy AS) and a decrease in enthalpy AH) is favorable. reverse Etf both these conditions AS and -AH) are met, the system is product-favored, if not, consider the of opposite signs of entropy and enthalpy. reaction, which has the if neither the forward nor the reverse reaction is favored in both entropy and enthalpy, then we cannot determine the favored direction without more information

Explanation / Answer

The reaction where change in standard enthalpy is positive....it is a endothermic reaction.....i.e we have give some energy to get the product. So at 298 k the reaction goes backwards...reactant favors.

And where the change in standard enthalpy is negative..then it is a exothermic reaction...i.e reverse of endothermic...and the reaction proceeds forward..and gives product.
